Hi all

Soon I'm going down south again and I'm sure I'll see terns again. The summer plumage terns are easy (they are always Antarctic Terns), but sometimes we find 'winter plumage'-like birds. Now, looking at what we find in the north, these could either be winter plumage birds (and thus Arctic Terns) or second summer birds (and thus Antarctic Terns). However, it's very difficult to find a proper comparison between these two.

Does anyone has an article comparing these two, or in other way experience to help me with these?

Regards, Arjen
